Continuity: In the episode "Team Diffy," Lloyd tells Andy that he noticed Andy had The Time Flyer 3000. But when Keely, Phil, and Andy are outside talking about if Phil would do Andy's prank, Andy says he is going to fire up The Time Flyer 2000, which is not the same one Lloyd noticed.

Continuity: When Marla pours the smoothie down Phil's top, she pulls it open and tips it to the bottom, presumably landing in his lap, and there's no smoothie on the chest of his sweater, but later when he's walking with Keely, the stain is on his chest.

Revealing: Season 2, episode 2 "Virtu-Date": When Pim is jumping rope with the girl, she is building a card house. When she jumps you can see the tape holding it together.

Plot hole: In the episode "Where's the Wizard?", when Pim gets the Wizard from Lil' Danny, she holds it in her hand. When Lil' Danny steals it, he takes it out of Pim's backpack, meaning it must be Pim's Wizard. But when Phil points it out, she says it's hers. This could be a character mistake, but if it was Phil's Wizard, they would not be able to track the one Hackett had, because inputting the signal of Phil's Wizard would do nothing.

Continuity: In the pilot episode, Keely is just becoming friends with Pim because she needs tutoring in algebra. In one of the final scenes, Pim comes up to Phil during lunch and says their dad called, so it's time for them to go home. When you first see Pim her necklace is undone, then when they are getting up to leave Pim's necklace is clasped.

Revealing: In the episode where Phil tries out for the gymnastics team, when he is on the bar you can see it's not Phil, and "Phil" has those special gymnast gloves on that disappear when he dismounts.
